Abstract
Disclosed herein is a novel cell line of human pancreatic cells that secrete insulin in a glucose-dependent manner. The cell line comprises pancreatic cells, such as PANC-1 cells, which are transfected so as to express IDX-1 and cultured in GLP-1. The cell line may be used to investigate the function and development of pancreatic cells, as well as to test the efficacy of drugs that stimulate insulin secretion.

10. A method of producing insulin-secreting cells that exhibit a dose-dependent response of insulin secretion when exposed to glucose, comprising:
-
transfecting a line of exocrine pancreatic cells with genetic material selected from the group consisting of IDX-1 DNA, IDX-1 cDNA, and IDX-1 mRNA; and
culturing the cells in glucagon-like peptide-1 (GLP-1). - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of determining the ability of a drug to stimulate cells that exhibit a dose-dependent response of insulin secretion when exposed to glucose to secrete insulin, comprising:
-
exposing exocrine pancreatic cells that have been transfected with IDX-1 cDNA and cultured in GLP-1 to the drug; and
measuring the amount of insulin secreted by the cells. - View Dependent Claims (29, 30)
